Thanks, sir. As the Gitanjali Express originates from Mumbai CST, could it be that it's highly improbable (if not outright impossible!) that I may get confirmed seating in the 2S class? Is the 2S class different from the GEN coaches (the Gitanjali Express, it appears, has 3 GEN coaches), or, are they the same? GEN coaches would mean totally 'Unreserved' coaches (i.e., a 'free-for-all') -- am I right here? Please advise.
